Abstract

Polyamic acid (PAA) furyl alcohol (FA) and their mixtures in different ratios were investigated by DTA. The effects of the solvent and the component ratio on the thermal characteristics of the final products were established. It was shown that when the PAA-FA composition is heated, PAA is the initiator of the polymerization of FA, and the interaction in the system is profoundly affected by the component ratio and the temperature.

The existence of an interaction between the components of the system was confirmed by TG, and IR and NMR spectroscopy.

Zusammenfassung

Mittels DTA wurden Polyamidsäure (PAA), Furylalkohol (FA) und deren Gemische verschiedenen Verhältnisses untersucht. Es wurde der Einfluß des Lösungsmittels und des Komponentenverhältnisses auf die thermischen Eigenschaften der Endprodukte festgestellt. Es konnte gezeigt werden, daß beim Erhitzen der PAA-FA-Gemische PAA die Rolle des Initiators der Polymerisation von FA übernimmt und daß die Wechselwirkungen im System von Komponentenverhältnis und Temperatur grundlegend beeinflußt werden. Die Existenz der Interaktion zwischen den Komponenten des Systems wurde durch TG-, IR- und NMR-Spektroskopie bekräftigt.

Резюме

Методом ДТА изучены п олиаминовая кислота (ПАК), фурфуриловый спир (ФС) и их смеси в различных соо тношениях. Установле но влияние растворителя и соотн ошения компснентов на термические харак теристики конечных п родуктов. Показано, что при нагр евании смесей ПАК-ФС, ПАК инициирует полимеризацию ФС, а взаидействие в систе ме в значительной степени затрагивает ся соотношением комп онентов и температурой. Наличи е химического взаимодействия межд у компонентами систе мы подтверждено метода ми ТГ, ИК- и ЯМРспектрос копии.
